IMPROVEMENT IN PLASTERERS TROWELS.

Specification forming part of Letters Patent N 0. [82,505, dated September 19, 1876; application filed August 17, 1876.

To all whom it may concern:

Be it known that we, WALLAcE WILLIAM- SoN and WILLIAM H. GREASER, both of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Plasterers Trowels; and we do hereby declare the following to be a clear and exact description of the nature thereof, sufficient to enable others skilled in the art to which our invention appertains to fully understand, 'make, and use the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a side elevation of the trowel. embodying our invention. Fig. 2 is a top or plan View, partly sectional, in the line a m, Fig. 1. Fig. 3 is a central longitudinal section. Fig. 4 is a bottom View. Fig. 5 is a central longitudinal section of the tang of the shank and the handle.

Similar letters of reference indicate corresponding parts in the several figures.

Our invention consists of a transverse and longitudinal re-enforce for the blade of a trowel, whereby said blade will be s ti fened' and braced at its weak points'fafid cracking thereof'is avoided.

Referring to the drawings, A represents the blade of a plastercrs trowel, B the handle, and O the shank. With the shank 0 there is formed a re-enforce, D, which consists of a longitudinal bar, E, with lateral bars F, and said re-enforce is riveted to the back of the blade A, the rivets a passing through th e e nd It will be seen that the blade is stiffened and braced in the longitudinal and transverse directions thereof by the angular re-enforce, and the weak ;spots or points which are at the sides of the center of the blade, both in the length and breadth thereof, are greatly strengthened, and prevented from cracking and breaking. G represents the tang, to which the handle B is attached, and it is screwthreaded,'as at b, so that'tlfi f liafidlema'ybe" readfl quickly, andfirnily connected thereto By this construction thehandle will be prevented wearing and rolling, heading of the tank is oby i ated, and liability t splitting the handle 'overcome; and should the handle loosen, the plasterer need only rotate said handle in order to tighten it on the tang.

We are aware that it is not new to apply a longitudinally-extending rib to the back of the blade of a trowel; but we are not aware WALLACE WILLIAMSON. W. H. GREASER.
